Google BigQuery error: Unable to refresh access token: invalid_grant. reauth related error (invalid_rapt)"

Hello, Zapier newbie here.

I’m evaluating using Zapier to create an alert system that is triggered off a “Query Job Completed (With Row Data) in Google BigQuery” Trigger.

When I first set this connection up, it was working for about a day, but now every day after, I’m getting an Alert email saying the Zap is having errors where I basically need to reset my connection. 

The error given is:

 Trigger partner failure: Unable to refresh access token: invalid_grant. reauth related error (invalid_rapt)


Additionally, when I go to the Apps → Google BigQuery → Connections → Test Connections flow, I get the popup stating:

Error testing connection.


This is all resolved by reconnecting the account through google’s SSO login, but this isn’t really workable long term. Any thoughts if the error is a setting on Google, or if it’s something about Zapier?


Thanks for the help!

Does zapier support connecting to BigQuery with a service account?

Hey there, @mtarnghn! Sorry to hear you’re running into this. 😔

I did some digging and it looks like you’re experiencing a known bug with Google BigQuery where the connection seems to be expiring every 12h or so. 😔

While I don’t have an ETA on a fix, I did add you as impacted user. This way you’ll be emailed once a fix is ready. We’ll also be sure to keep the topic updated as well. 

Thanks for flagging this in the community and welcome! 🙂

I’m experiencing this same issue, which makes Zapier unusable for me… Can you please raise this in priority?

Hi I’m experiencing the same issue here. 

This makes the BigQuery app completely unusable.

Has there been any update or do we have an ETA on the fix?

Hey folks! 👋

Hopping by with a quick update to share that the bug report for this issue has now been closed. It turns out this issue is caused by the Reauthentication Policy settings in Google Admin console.

To resolve things you can:

  • Set Zapier as a Trusted App and then exempt Trusted Apps from reauthentication.
  • Alternatively, you can change the settings to never require reauthentication for any app.

See for more details on this. Once you have changed your settings in Google Admin, please reconnect your Google account with Zapier.

If you’re still seeing issues after carrying out the above steps please let us know. In the meantime, happy Zapping! 😁⚡
